The main types of waste generated by the mining and milling of uranium ore are tailings and waste rock. Tailings are the waste produced by grinding the ore and the chemical concentration of uranium. When dried, tailings have the consistency of fine sand. Waste rock is simply rock material removed from the mine to gain access to the ore.

Uranium — How Is It Mined?

The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry. This slurry is then mixed with sulfuric acid or an alkaline solution to release the uranium from the host rock. Normally approximately 95 - 98% of the uranium can be recovered from the host rock.

Where Does Uranium Come From? - Nuclear Energy Institute

Ore mined from open-pit and underground mines travels to a conventional mill, where it is crushed, ground and leached to dissolve the uranium. Most of the ore is barren rock or other minerals that are not dissolved in the process. These solids, also called tailings, are separated from the uranium solution, usually by allowing them to settle out. Solvents or ion exchange processing removes the uranium from …
